I cross-post this to www-talk, as WWW should be aware of EDI.
For wwwwizads: There is discussion
in ietf-edi for doing EDI (electronic commercial transactions) over
the Internet. EDI seems to be like using forms with email submission,
with a forms language which HTML+ _ought_ to be able to subsume.
I suggest someone get hold of the specs and write a DTD which is
equivalent. Whether you like the look of the EDI format or not
(if you are a WWWWizard I can hazard a guess ;-) there is an established
community using this stuff and so the standards must reflact needs in
some way at least. A good test of a new, general, system, is that it
can represent other things without pausing for breath. This is what
WWW rather specialises in. First thing is to get hold of X.435....
We will soon have apparatus for interactive transactions with forms
operating in I suspect a largs scale on the Internet for applications
which are not legally and financially critiacal. Forms with HTTP are
much faster and neater than anything email or even "fast batch"
as they say in EDI. PEM on top of HTTP will introduce the security,
and then there will suddenly be a complete Internet solution for EDI
as a spin off of what we have now. We don't want then that there is
some basica incompatibility with EDI. That's why I suggest someone
check out the specs. I suspect Dave Raggett won't have time soon,
so is there a volunteer?
Now to the message I quote:

Aaaagh, the Internet spirit!

I would be interested in a copy -- anyone prepared to fax
it to me even if its not online? Or is there an ECMA
equivalent number for this ANSI spec?

HTTP is a bit ahead of MIME with the forms DTD here --
as HTTP uses MIME for messages (just does them interactively)
it shouldn't make a lot of difference.

Just watch HTTP.

Aside from that, do we really want to draw the line and say that
a particular information item is commercial, and therfore
shough use one paradigm, set of protocols, etc, and another
is not really commercial so will use the same pardigm as
the web, news, and mail? Of course not. Such lines do not
exist. We want to put the features, such as security and
common formats, in in a totally orthogonal way, so that they
can all be blissfully used together. And it shouldn't be
difficult. :-)
